| 中文摘要: |
| 讨论了离散小波变换在语音去噪中的应用.根据语音中浊音段和清音段的特点,采用了不同的阈值方案,可以保证在失真较小的前提下,获得更好的去噪效果. |
| 英文摘要: |
| In this paper, an application of wavelet transform for speech signal denoising is discussed. According to the properties of voiced segment and unvoiced segment in speech signal, we use different thresholds. And a better effect of denoising is derived with less distortion. |
